The Feasibility and Effectiveness of the Simultaneous Recording of Ocular and Cervical Vestibular-evoked Myogenic Potentials / 听力学及言语疾病杂志

ABSTRACT

Objective To study the feasibility of simultaneously recording ocular vestibular-evoked myogenic potential (oVEMP) and cervical vestibular-evoked myogenic potential (cVEMP) by combined oVEMP and cVEMP tests.Methods Twenty healthy volunteers and twenty-three patients with Meniere's disease were admitted and underwent combined oVEMP and cVEMP tests in a random order,and individual oVEMP and cVEMP tests on another day.The results of combined and individual oVEMP and cVEMP tests were compared.Results For twenty healthy volunteers in oVEMP and cVEMP tests,the 100％ response rate were observed in the both combined and individual test modes.The differences in amplitudes and latencies and interaural amplitude difference were insignifi-cant.For twenty-three patients with Meniere's disease,the results of oVEMP/cVEMP for the affected and unaffected ears failed to sow any significant differneces,regardless of the individual or combined mode.Conclusion The simultaneous recording of oVEMP and cVEMP by the combined mode has similar results to that obtained by individual mode for both healthy or unilateral vestibular hypofunction.Simultaneous oVEMP and cVEMP tests may be a convenient screening test and deserves further clinical applications.
